Abstract (en)

[origin: EP1162515A2] A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus includes an electrophotographic photosensitive drum; a developing member for developing an electrostatic latent image formed on the electrophotographic photosensitive drum; a developing frame (17) having a developer accommodating portion (16) for accommodating a developer to be used for developing the electrostatic latent image by the developing member, wherein the developer frame is provided with a developer supply opening for supplying the developer accommodated in the developer accommodating portion toward the developing member; a connecting member (33) mounted to the developer frame (17), the connecting member (33) being provided with a connecting member opening opposed to the developer supply opening; a drum frame (13) supporting the electrophotographic photosensitive drum; a developing frame (17) supporting the developing member, the developing frame being movably connected with the developer frame (16) by a flexible seal (21), wherein the developing frame is provided with a developer receiving opening for receiving the developer having passed through the developer supply opening, wherein the flexible seal is provided with a first opening and a second opening, wherein the first opening is opposed to the developer supply opening and the connecting member opening, and the second opening is opposed to the developer receiving opening, wherein the flexible seal is stuck on the connecting member at a periphery of the first opening, and is stuck on the developing frame at a periphery of the second opening, and wherein the flexible seal is made of a sheet which is folded back such that the first opening and a second opening are opposed to each other, and ends of surfaces of the sheet which are opposed to each other as a result of folding are stuck to each other.
